MECHANISM FOR ADJUSTING FORMS OF SOLE-LAYING MACHINES.

SPECIFICATION forming part of Letters Patent No. 610,315, dated September 6, 1898. Application filed March 26, 1.897. Serial No. 629,410- (No model.)

The present invention relates .to improve ments in machines for temporarily securing the outsoles of boots and shoes to the lasted insole and upper, commonly known in the trade as sole-laying.machines, and more particularly to that type of sole-laying machines in which the shoe is supported upon its last, held in a suitable jack, and the outsole, previously provided upon its under sur-' face with a layer of cement and placed upon the bottom of the insole, is acted upon by a mold or form under the required pressure to cause the same to assume approximately the form required in the finished boot or shoe and to set the cement, which holds it in position until permanently united with the other elements of the shoe by stitching or other suitable means.

The molds or forms for the class of solelaying machines above defined are commonly provided with a yielding pressing-face toenvary the length of the heel and toe portions.

It has been foundin practice to be of the greatest importance to properly position the pressing-face of the form, and particularly the shank portion thereof, for' the variations above suggested; and to this end the present invention consists in providing, in a sole-laying machine, means for longitudinally and laterally adjusting the form to position its pressing-face, and particularly the shank portion thereof, for different sizes and shapes of last.

A preferred form of the present invention is illustrated in the accompanying drawings, in which Figure 1 shows a portion of the form-carryinglever of asole-laying machine in broken section and the mold or form in side elevation, and Fig. 2 shows the same parts in plan view.

Similar letters of reference indicate like parts in both views.

In the drawings, A represents aportion of the form-carrying lever of a sole-laying machine upon which is mounted the form B and by which said form is brought in contact with the sole with sufficient pressure to perform the sole-laying operation.

The lever A may be and conveniently is similar to either of the levers shown and described as used for a similar purpose in Letters Patent of the United States No. 557,744,

issued to me April 7, 1896, and serves to illustrate the application of my invention to my said patented machine. I do not, however, desire to limit my invention to its application to said patented machine, as it is evident that with slight modification it is applicable to analogous machines.

The formB, as shown, comprises the usual rigid bed portion 1), having the general longitudinal contour of the bottom of a last and carrying and supporting the elastic pressingpad I), which is provided with the usual projected shank portion b all of which parts, except as hereinafter specified, may be of any usual and convenient construction, and their form and arrangement may be changed in many ways without any departure from the present invention.

In accordance with the present invention I have provided means for longitudinally and laterally adjusting the form B to position its pressing face, and more particularly the shank portion thereof, for different sizes and shapes of last, said means, as embodied in the form of my invention shown in thedrawings, comprising the following mechanism.

The bed I) is mounted upon a short shaft or cross-bar a, which spans an opening a in the lever A and is mounted to rotate in bearthe cross-bar a.

ings in the lever A, being, however, held from longitudinal movement in said bearings by suitably-placed collars (not shown) or other convenient means. The bed I? is secured to the cross -bar a by means of the bearingblocks 19 which are placed upon opposite sides of the bar a and form a divided bearing 19 for The bearing 17 is of slightlyless diameter than the cross-bar a, so that when the blocks b are drawn together, as hereinafter described, they pinch the bar CL, and are thereby held from lateral movement along the same. The blocks 19 are conveniently held together by means of the bolts 17 which pass through the elongated bolt-holes Z1 (elongated longitudinally of the form,) formed in the blocks b and engage threaded bearing b in the bed Z), preferably in a flat tened boss 6 formed thereon, the upper surface of the boss b forming a bearing'for the lower surface of the lower block I also provide in practice a clamping washer-plate b which rests upon the upper surface of the upper block b and through which the bolts 19 pass, the heads of the bolts b overlapping and bearing upon the washer-plate b.

The above-described arrangement is such that by loosening the bolts?) the blocks 19 may be moved laterally along the bar a, the opening a being sufficiently wide to allow such movement, and the form B moved laterally to laterally adjust its pressing-face and laterally position the shank portion thereof, and at the same time the elongated bolt-holes b permit the form B to be moved longitudinally to longitudinally adjust its pressingface and the projected shank thereof. hen the adjustments above noted have been made and the form B is in itsproper position, by

setting up the bolts 6 the blocks 5 are drawn together to pinch the cross-bar a, and the lower block b is firmly clamped against the boss 19 and the form B thereby firmly held from lateral and longitudinal movement.

In practice I provide the boss 11 with a longitudinal rib 79 which engages a corresponding groove Z9 on the block 19 which takes up any lateral strain on the bolts 19 and prevents any torsionalmovement of the bed I), and the blocks 5 are conveniently provided with the usual centering-pins I).

It willbe noted that when clamped in position as above stated the form B is free to tip longitudinally with the cross-bar a, so that it can automatically assume the required longitudinal inclination.

I have in the foregoing description of my invention and in the following claims referred to lateral and longitudinal adjustments of the sole-pressing form. By lateral adjustment is meant an adjustment of the form from side to side or with reference to the width of the boot or shoe sole, and by longitudinal adjustment is meant an adjustment in the direction of the length of the sole.

Having heretofore sufficiently described the operation of my improved form as shown in the drawings, I claim as novel and desire to secure by Letters Patent of the United States- 1. The combination with a suitable carrier, of a block supported on said carrier, a solepressing form secured to said block, means for laterally adjusting the block and form on said carrier, and adjustable connections between the form and block for longitudinally adjusting said form, substantially as described.

2. The combination with a suitable carrier, of a swinging block supported on said carrier, a sole-pressing form secured to said block, and adjustable connections between said block and form for longitudinally adjusting said form, substantially as described.

3. The combination with a suitable carrier provided with a shaft or cross-bar, of a solepressing form mounted for a lateral adj ustment on said cross-bar, and means to fixedly secure said form in its adj usted position upon said bar, substantially as described.

4:. The combination with a carrier provided with a shaft or cross-bar, of slotted bearingblocks mounted upon said cross-bar, and a sole-pressing form longitudinally adjustable upon said bearing-blocks, substantially as described.

5. The combination withacarrier provided with a cross-bar or shaft, of bearing-blocks mounted upon said cross-bar or shaft, slots in said bearing-blocks, supporting-bolts arranged in the slots, a sole-pressing form supported by said bolts, and a rib upon said form engaging a groove in the lower face of one of the bearingblocks, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
